To all whom it may concern:

Be it known that I, JOHN B. CLERMoN'r,

of New York, in the county of Bronx, and in the State of New York, haveinvented a certain new and useful Improvement in Ap paratus and Packagesfor Forming Solutions by Percolation, and do hereby declare that thefollowing is a full, clear, and exact description thereof.

The object of my invention has been to provide an apparatus for formingsolutions by percolation and a package of material for use in suchapparatus, which shall be adapted, among other uses, for use in makandwhich shall have any or all of the fol owing advantages! That of greatsimplicity; that of enabling infusions to be made of such substances ascofi'ee by passing the water or other liquid but once through thematerial being leached;

' that of enabling the material being leached to be introduced into theapparatus and remain therein in the form of a package so as to providenot only for simplicity of 26 pperation, but for easily cleansing theapvation, a vertical sectional view, and a bottom plan view of acartridge or package ada t'ed for use with said apparatus.

y invention is capable of use for many different purposes, and while Ihave chosen for illustrating it the best form of apparatus known to me,suchapparatus and packa e for use therewith, are to be regarded as on yone of many possible embodiments, and my invention is not to berestricted thereto.

The illustrated embodiment of my invention is adapted particularly forthe manufacture of coffee. In such embodiment, I

have shown a base lwhich is adapted to fit over a cup or othervesselinto which the made coffee is to drop, such cover having. a

' flange 2 at its outer edge to prevent its escaping from off the'cup.In the center of the base is a sleeve 3 which is solderedor otherwise.fastened to the base, and which is provided with an inturned flange 4 atits Specification of Letters Patent. Patented A 11 1922 Applicationfiled January 11', 1916. Serial in. 71,418. 5

lower edge. pot or body 5, is provided w th a neck 6 that is adapted tobe received within the sleeve, and to rest upon the flange 4, the neck 6also having an inturned flange 7 at its lower edge. A bayonet joint isformed between the sleeve and the neck by plus 8 on the neck, adapted toengage cam slots 9 1n the sleeve. A cover 10 is provided for closing theupper end of the pot.

The coffee or other material from which the infuslon is to be formed isprovided in what I term cartridges, or packages adapted to be receivedwithin the neck of the pot, such packages preferably havingsubstantlally vertical walls llthat are sufiiclently mpervious to wateror other infus- 1I1P liquid so as to compel all the water escaping fromthe lower end of the neck to is seated a disc 14 of material which willpermit the passage of the water or other lniuid while preventing theescape of the so id material, and such disc may be formed of unsizedpaper like blotting paper. The paper or other material forming theshoulder 13 is preferably turnedover underneath the disc 14 to, secureit in place. A

disc of porous paper may also be used to close the perforations'lZ inthe cartridge. Both the upper and lower ends of the car-- tridge may besealed as by seals 15 and 16 formed, for instance, of paraffine tissuepa er, and which are easily torn ofl.

n the use of m apparatus and cartridge, the cartridge, loa ed withpulverized cofl'ee, is made ready for use by tearing off the thin seals15 and 16, and is placed in the neck 6 of the pot by inserting it in theneck when the pot is inverted, so that the shoulder 13 of the cartridgerests'on the flange 7 of the neck. The sleeve 3 is then placed over theneck and by means of the bayonet joint is caused to clamp the shoulder13 and filter disc 14 between the flanges 4 and 7, so as to make asubstantially water-ti ht joint.

The pot is then supported upon t e cup on T other receptacle which is toreceive the cofiee extract, and the required amount of water is pouredinto the pot through its top. The water percolates through thecartridge, and as it can only enter through the perforations 12 and onlyescape through the porous paper disc, all the water has to pass entirelythrough the layer of coffee and is all thus equally presented to thepulverized coffee. The result is that the water is in contact with thecoifee long enough to take up its beneficial extracts but is not, incontact long enough to dissolve its harmful in gredients. In this way,although the water my pass but once through the ground coffee, fluidcoffee of the finest flavor may be obtained and with the least amount ofdeleterious substances therein, and it is found that substantially allof the beneficial materials in the coffee can be extractedwith thesingle passage of the Water therethrough.

It will be seen that my apparatus and cartridge have, among others, thefollowing advantages, in addition to those just described:

The use of the cartridge enables the material being leached to beintroduced into the apparatus and removed therefrom Wltlh out everlosing control of the material, so that not only is the operation ofcharging and emptying the percolator performed with great simplicity andcleanliness, but an infusion is obtained of the greatest possiblestrength, and all the material being leached is insured of thorough andequal treatment by the water or other liquid. .Regulatin the size of thecartridge is' a convenient an accurate means for measuring the properamount of coffee or other material to form the desired quantity of theinfusion. The apparatus is of great simplicity and can be used out ofdoors without other facilities than those for supplying hot water.

Itis obvious that various changes can be made in the above describedembodiment of my invention which would be within the scope of theinvention. For instance, the cartridges may be charged with more than asingle substance, such, for example, as with coffee and milkin a driedform, as well as sugar.

I claim:

1. In a percolatin nation of a receptac e having a cylindrical neck,a'cap having a cylindrical sleeve adapted to fit said neck, said neckand sleeve hav- 1n sald neck and sleeve, means for forcing said flangestoward each other, and a cartridge having a pervious topand bottom, saidcartridge having a shoulder adapted to be clamped between said flanges.

2. In a percolating a paratus, the combination of a receptacle iiaving acylindrical neck, a cap having a cylindrical sleeve adapted to fit saidneck, said neck and sleeve having inturned flanges on the lower end ofapparatus, the combiinturned flanges on the lower end of said neck andsleeve, a bayonet joint adapted to force said flanges toward each other,

. and a cartridge having a pervious top and bottom, said cartridgehaving a shoulder adapted to be clamped between said flanges.

3. In combination, a receptacle adapted to contain liquid, a baselocated beneath said, receptacle and having portions shaped to fit overa receiving vessel, said receptacle and base having parts adapted-toreceive therebetween an independent cartridge containing material to betreated, and a bayonet pin gether said receptacle, and base.

4. In a percolating apparatus, the combination o a receptacle, and abase each having a cylindrical neck or sleeve, said them, and acartridge having a pervious top and bottom, said cartridge having a.shoulder adapted to be clamped between said flanges.

In testimony that I claim the foregoing I have hereunto set my hand.
